According to El Reg (http://www.theregister.co.uk/2007/03/28/domain_appraisal_scam/), there's a scam going on targeted at domain owners. "Typically the sophisticated fraud, which is still under investigation, starts with an email message to domain owners offering to purchase a domain. Prospective marks are directed to a forum ostensibly set-up to discuss domain appraisal services."
I'm sure members would be wary of such a scam, but just in case...
